What You're Up Against
Level 121 paints Boat with 213 tiles across 4 colors, split into 8 cubes in the tray. You have 5 waiting slots and two nest holes.
- Cyan: 96 tiles → cubes of 39, 38, 19
- Indigo: 69 tiles → cubes of 39, 25, 5
- Orange: 30 tiles → cubes of 30
- Pink: 18 tiles → cubes of 18
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Cyan 38
Step-by-Step Solution
This loading order was computed from the web level layout with a reachability-first strategy: always feed the ants colors they can actually reach, and never let all 5 slots fill with blocked colors. Tap hidden “?” cubes only when you have slot room to absorb a surprise color.
Load the cubes in this order, letting the ants work between picks. Unless noted, a cube's tiles are fully reachable when you send it.
- Send the Cyan 19 cube.
- Send the Indigo 5 cube.
- Send the Cyan 38 cube. Only ~27 of its 38 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Cyan 39 cube. Only ~19 of its 39 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Indigo 25 cube.
- Send the Indigo 39 cube. Only ~28 of its 39 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Orange 30 cube. Only ~14 of its 30 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Pink 18 cube.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
